Development of a highly potent, selective, and cell-active inhibitor of cysteine cathepsin L-A hybrid design approach

Abstract

A hybrid-design approach is undertaken to develop a highly potent and selective inhibitor of human cathepsin L. Studies involving human breast carcinoma MDA-MB-231 cells establish that this inhibitor can successfully block intracellular cathepsin L activity, and retard the cell-migratory potential of these highly metastatic cells.
